Cooperative communications achieve tremendous improvements in system performance. Meanwhile, it tends to change the conventional access and transmission schemes in wireless networks. Thus, CoopMAC is proposed and analyzed for fully connected WLANs. It improves the performance of the network dramatically by enabling additional collaboration from other nodes. However, how does it work in multi-hop Ad...
The purpose of this paper was to model the daily stem water content with neural network. The output voltage of stem water content sensor changed as time series. In order to ensure the accuracy of the model, coefficients sc and eg must be adjusted with the RBF NN input vector changed. The dimensions of input vectors were grouped from 2, 4, 5 separately. After being grouped, observed data were input...
The phenomenon of churn degrades the lookup performance of DHT-based P2P systems greatly. To date, a number of approaches have been proposed to handle it from both the system side and the client side. However, there lacks theoretical analysis to direct how to make design choices under different churn levels and how to configure their parameters optimally. In this paper, we analytically study three...
An ultrafast time-resolved UV/visible absorption study of the UV photochemistry of [CpFe(CO) 2 ] 2 (Cp = η 5 -C 5 H 5 ) in cyclohexane solution has shown that the long-lived CO-loss product, Cp 2 Fe 2 (μ-CO) 3 , is produced within 40 ps. The immediate precursor has a lifetime of 15 ps and may be assigned preliminarily to the coordinatively...
